13 Reasons Sustainable Timber is the Best Construction Material
Timber is a wonder material with many functional, aesthetic and environmental benefits. Here's 13 reasons why it's the best construction material.
Cladding material
Plastic materials like polyethylene, acrylic/polyester, polyester, and fiberglass reinforced plastics are common cladding materials for greenhouses. Polyethylene is relatively short-lived but transmits 85-88% of sunlight. Acrylic/polyester combines weatherability and heat resistance but is susceptible to wind damage. Polyester has excellent transmittance and heat resistance but limited widths. Fiberglass reinforced plastics are more impact resistant than glass but proper installation is important. Shade nets made of plastic are also used as cladding to protect crops from weather.
Cladding
The document provides an overview of different types of cladding systems. It defines cladding as an exterior finishing system that protects the underlying structure and provides decorative finish. There are many types of cladding including dry wall, wet wall, weatherboard, timber, stone, external foam, metal, concrete, and brick cladding. The major purpose of cladding is to separate the indoor and outdoor environments to maintain suitable indoor conditions by keeping water out, preventing air leakage, controlling light, heat radiation and conduction, and controlling sound.
BUILDING MATERIALS AS A PLASTIC
Plastics are widely used in building construction and materials. They are used for roofing materials, cladding panels, sound and thermal insulation, decorative laminates, adhesives and sealants, and more. Plastics provide advantages over traditional materials like being lightweight, resistant to rot and weather, and requiring little maintenance. Common plastics used in buildings include polycarbonate, PVC, polystyrene, and foams for insulation. While plastics have advantages, they can also soften at high temperatures or become brittle in cold.
Wooden cladding
Wooden cladding offers several advantages for building exteriors, including design freedom, ease of installation, and ability to withstand stresses. Proper installation is important to prevent moisture damage - cladding should be sealed and finished before installation, with flashing added at joints and openings. Regular maintenance of finishes helps protect the cladding from swelling, shrinking, and discoloration over time.
Insulation: Wrapping It Up
The document discusses the history and types of insulation. It covers:
1) Insulation has been used since ancient times by cultures like the Mayans, Egyptians, Greeks and Romans to regulate temperatures in buildings. Common early materials included mud, straw, and tapestries.
2) Modern insulation materials aim to reduce heat transfer through conduction, radiation or convection. Common types discussed include fiberglass, mineral/rock wool, foam insulations, and natural fibers.
3) Proper insulation of a building's envelope is important for thermal comfort and energy efficiency. It can reduce heating and cooling costs by around 20% on average.

Iron and Steel Technology towards Sustainable Steelmaking
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
